From Phil Jones:

The DOUBLE FOUR is the pinnacle of micro bass amps. With new driver design, acoustic loading and the latest digital amplifier technology, this tiny bass combo may be designed as a practice amp but continues to amaze everyone with the great PJB signature bass tone. From a cabinet with size of a jewel box, this seems to defy the laws of physics.

Driver and Amplifier Technologies:
Pushing our expertise of using smaller drivers to get the ultimate bass sound, we applied our vast experience to an even smaller, “Neo Power”4 inch driver built with precision of a Swiss watch. This 4” baby is able to cope with the extreme signals coming in from an amplified bass guitar. By using our extensive R&D facility which includes the largest anechoic chamber in the bass guitar amplifier industry, and the KLIPPEL transducer measurement system, we were able to develop the perfect 4 inch transducer for our purpose. We analyzed the neodymium magnetic system, the cone behaviors at all frequencies in 3D representation, cone suspension and frame, until we achieved our goal. We then looked at the acoustic loading using the acoustic simulation software and calculated exactly the full power cone displacement at every frequency.

Each one of these 4” speaker is fed with its own Pulse Width Modulation PWM amplifier. PWM amplifiers are extremely efficient compared to the traditional analog solid state amplifiers, converting electrical energy to power using on the speakers instead of wasting it on hot. Since the amp is running at lower working temperature, the DOUBLE FOUR will give years of service long after other amps have faded away. By using dual amplifiers one for each speaker, the bass control is greatly improved since the damping factor ( the amplifier’s ability to put on the “brakes” to stop the speaker cone from overshoot ) is doubled. The end result? A bass tone that is well controlled, punchy, tight and never muddy or bloomy.


Enclosure Technology:
To maximize its tiny cabinet enclosure, we designed a custom Rectangular Auxiliary Low Frequency Radiator (RALFR®). RALFR® is a pneumatically coupled radiator loaded to the rear of the two 4 inch speakers that operates at the lowest bass frequencies only. It augments the output of the loudspeakers at frequencies from 30 to 150 Hz. It also reduces the cone excursion of the speakers, so power handling is greatly improved. The cabinet is also heavily braced internally and lined with acoustic damping materials. This damping prevents cabinet coloration that can interfere with the true sound of your instrument. Now, what you hear from the DOUBLE FOUR is the most realistic amplification of your instrument.

We're right off the CTA Brown Line 'Paulina' Stop Just North of Belmont and just West of Ashland.

We’re all musicians here at Chicago Music Exchange and we want you to love the gear you get from us. We understand that sometimes you get a piece of gear that doesn’t work out for you. That’s why we offer an easy return policy to take the stress out of purchasing from us.

If you decide you'd like to return an item, please contact your Sales Rep, chat us, or give us a call.

If you placed your order on Amazon or eBay, we advise issuing the return request from your account on the platform of purchase - our Customer Service team will process a refund upon receipt of the item(s).

Most new items may be returned within 30 days of delivery and most vintage & used items may be returned within 3 days of delivery for a full refund, exchange, or store credit. Please pack the product safely for the journey back to us. If the product was shipped for free, the charge will be deducted from refund, unless the reason for the return is outside normal circumstances.

Please contact us as soon as possible if your order was received incorrectly, damaged, or defective. Most times we will give you an RA number (Return Authorization). Why is that number important? This will allow us to speed up the process of the return.

We reserve the right to charge a restocking fee based on the return condition. Some items we just can’t take back for returns, due to a one time function like strings or drums heads and other times it’s not sanitary to do so with microphones or harmonicas. If you aren’t sure if what you bought falls into a category like this, call us (773) 525-7773!

We strive to get your return processed quickly. Most of the time we have it done within two business days. Funds going back to credit cards usually takes two to four business days.
